Cause

Note

First digit is not illuminated from 0:01.01 to 9:59.59 in 12 or 24-Hour configuration.

Analyze

Initiate a reset.

Either power cycle the clock or initiate a manual reset.

A power cycle or manual reset causes the clock to scan for a broadcasting Transmitter. The clock initiates its power cycle/reset sequence as described below.

All LED segments display 8s with a red dot on the bottom right of each of the two hour digits and one at the second or last minute digit.

All LED segments display dashes and then dashes with a colon between the hours and minutes.

Once the clock/timer receives a signal from the Transmitter, the LED segments display the time received from the Transmitter and a flashing red dot appears at the bottom right of the second hour digit for three minutes.

Solution

Reset the clock to search for a signal.

If a single or all segments fail to illuminate after a reset, the clock will be required to be replaced.
